I am running the MCC USB-1608GX with DAQami. As a test, I have the same sine wave connected to 4 different analog input channels (DE). I'm noticing phase differences in the signals being read from the four channels. These phase differences also seem to vary over time. (As one example, I'm seeing this with a 30 kHz sine wave, with all analog input channel sampling at 62.5 ksps) I suspect this is due to the ADC multiplexing. Is that the case? Is there any way to minimize this behavior, and/or adequately account and correct for it? Thanks!
